Has anyone got any idea at all where this screw might have come from?
I was doing some maintenance on my bike and this small screw fell to the floor as I turned my bike upside down. I cant for the life of me think where it could have come from.
I was removing my crank at the time but it doesnāt seem to be related to that.
Bonus points if you can read my palm and tell me how iām going to die - I would be especially interested if the answer was ābike accident caused by riding without critical small screw installedā
That was my first thought too - I looked at all the access hatches from the outside and couldnāt see anything - what just occurred to me now is that screw could have been rattling around in my frame for ages and just dropped out when my crank was removed. Iām going to have to take my crank back off and see if there is anything meant to be holding the BB hatch in place from the inside
Of course anything dropped into the frame would end up at the BB anyway - maybe some drunk begian dropped it in there when they built my bike? It looks pristine.
Itās certainly not the bolt you actually torque up, itās too small, but I canāt remember if the stopper design has any other screws that keep it together when itās not fitted.
It will occur when your wife crushes your skull with a Williams Sonoma marble rolling pin you received as a wedding gift from a cousin you barely know. Your wife will be crushing your skull because she will be on Meta reading about some other guy in some other country who allegedly spent years lying to his wife about āgoing for group ridesā, but was really just doing an inappropriate one on one ride with an overly friendly neighbor. Though youāve done no such thing, sheāll mistake the remnants of chammy cream on your bib shorts for another substance and go into a fit of uncontrollable rage. There will be great remorse afterwards and luckily, sheāll find comfort and future happiness in the arms of one of your former riding buddies when they get drunk at the wake.
Lol, I was going to say a chain ring bolt until I saw the zoomed out picture and saw how tiny it was I think I have seen small Torx head screws like that in electronic devices like computers or lights and I think Iāve saw some tiny like that to retain the brake spring or something.
It might help to have a full picture of your bike, but this looks like it could be a seat clamp bolt. The non-threaded section looks like it slips through a bracket and has a bolt on the back side for adjusting tilt.
The seat clamp is all held together with the one big bolt and explodes into loads of parts whenever you want to adjust the seat - donāt think itās that.
The seatpost clamp Iām not sure about - the bolt you torque up is obviously much bigger but Iām wondering now if there is another small bolt involved somewhere
I was wanting to click on like but liking news of someones death didnāt seem right to me. Lol, I think we need emotive replies in addition to a simple like
Thatās a solid guess and good analysis. I kept thinking that it looks like the screw for a derailleur jockey wheel, but the shank is too thin for that, the diameter would match that of the outer of the threads, and it would be pretty obvious if that went missing. A screw from a bar end plug wouldnāt be missed immediately.
